GOSSAMER FABRIC AND PROCESS OF MANUFACTURING THE SAME.

SPECIFICATION forming part of Letters Patent No. 34%,086, dated June 22, 1886.

Application filed March 27, 1886.

To aZZ whom it may concern:

Be it known that I, MYRON L. DERIOK, of Brockton, in the county of Plymouth and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Gossamer Fabrics and Process of Manufacturing the Same, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming'a part of this specification in explaining its nature.

The invention relates to that class of gossamer goods known as electric or silver-finished gossamer, or goods which are finished upon their surface with powdered potato-starch; and it consists in providing such goods with an ornamental or figured surface of any character or design, and also to the method or process of manufacturing the same.

Referring to the drawings, Figure l represents in perspective a portion of the mechanism employed in the process. Fig. 2 is a plan view of a portion thereof enlarged, showing the pattern or figure on the goods. Fig. 3 is alike view to that shown in Fig. 2, represent ing a somewhat different pattern or figure on the roll and goods. Figs. 4 and 5 are end views of the roll.

In the manufacture of the goods the fabric which forms the base or support for the rubher or water-proof surfacing is treated with one or more coats or layers of the water-proof or rubber composition. It is then surfacecovered with finely-pulverized potato-starch, and it is then, before it is sun dried or cured, immediately subjected to the action of the figuring-rolls, which impress upon the coated surface of the fabric the design or figure which it is desired it shall have. The fabric is then completed by exposure to the sun.

In the drawings, I have represented only so much of the mechanism as is used for producing the design or figure upon uncured goods; and A represents a plain or smoothsurfaced roll of suitable length, which is mounted in proper hearings or supports, (not shown,) and A is a roll placed above the first named, and having formed thereon the design or figure which it is desired to give to the surface of the fabric. This roll is also mounted in suitable bearings. The design or figure may be in the form of parallel bars, as would be Serial No. 196,746. (Specimens) produced by the roll shown in Fig. 2 of the drawings, or it may be of any other form of line-work, or in the form of squares, as shown in Fig. 3, or figured, or in fact of any form. or design that can be engraved or formed upon an impressing-roll The fabric, after it has received the last coating of water-proof material, and having been surface-coated with the potato-starch, is passed between the two rolls A A, and the rolls set upon it sufficientl y to cause the impression to be given to the surfacing-coating of the fabric, and the movement of the goods through the rolls is su'fficient to cause them to revolve.

The fabric, after it has been treated, is removed and finished or treated by exposure to the sun, and this sets the figure or design which has been previously formed or made, so that it becomes permanent.

The figure is formed not so much by impressing or sinking the surface of the material as by rolling such portions of the surfacing of potato-starch into the coating of the goods as the upper roll shall come in contact with as the material is passed by it; and this rolling action gives such portions of the fabric as come in contacttherewith a dull finish, which forms a contrast with the silvery finish provided by the potato-starch.

Of course I would not be understood as limiting the invention to a fabric in which the silvered effect or finish is obtained by potatostarch, as the same result would follow if any other finishing-powder of any other color were employed in lieu of the potato-starch.

I amaware of the British Patent No. 6,399, dated April 16, 1884, and also of the United States Patent No. 322,601, dated July 21., 1885, and of the process therein described; and I would say that I do not claim anything there in shown and described, as I do not make a fabric with a design in relief or in intaglio, as I do not use rolls for producing such design, as I do not cure the goods as therein stated, and as the character of the goods which I make is very different from those therein described.

Having thus fully described my invention, I claim and desire to secure byLetters Patent of the United States- 1. The process of manufacturing figured gossamer fabrics, consisting in. surface coating 10 with a water-proof composition, and having its surface provided with figures or designs by means of a finishing surfacing-powder, portions of which are rolled into the coating of the fabric, to provide a figure or design, substantially as described.
